    A hydroponic gardening curriculum by Philson A.A. Warner, Donald A. Rakow, and Charles P. Mazza

    This 44-page publication compiles ideas and activities using hydroponics to teach plant science, physics, entomology, social studies, nutrition, math and more.

    The ten-session curriculum built around a hydroponic growing unit -- a system for growing plants in water. In this project you and your group will construct and set plants in a hydroponic unit, watch the plants grow and harvest them.

    The curriculum is most suited to middle-school-aged youth, but younger and older persons can also tackle it.

    The hydroponics unit is simple to contruct from a standard fish tank or a plastic storage bin, PVC pipes and fittings, tubing, rock wool cubes, and a pump. Complete instructions for building two different hydroponic units are inlcuded in the publication's Appendix. (See Horizontal hyrdoponic unit plans for a sample.)
